SAFETY RAZOR.

Application led January 10, 1920. Serial No.350,488.

To aZZ whom t may concern.' u

Be it known that I, FRANZ A. FULLER, a citizen of the United States, residing in the city of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Safety Razors, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it pertains to mak-e, construct, and use the same, reference being had to the accompanying drawings, and to numerals of reference marked thereon, forming a part of this speciiication.

This invention relates to improvements in safety razors, and more particularly to such as are adapted especially for stropping the safety razor blades. My invention has for its object, the production of a safety razor having a frame adapted to slide longitudinally of a strop, a blade holder being pivotally supported in said frame and means for rocking the blade while in the frame, for stropping the edges thereof. Another object of my invention is to provide means to cause aI strop to rock a pivotally supported blade holder with its pivotally supported blade in such a manner as to prevent the blade from cutting o1' injuring the strop, and also having means for positively adjusting the blade relative to the guard teeth.

lVith this end in View, my invention consists in certain novelties of construction and arrangement of arts as hereinafter set forth land pointe out in the claims. While the preferred forms of my invention are illustrated in the accompanying drawings yet it is to be understood that minor detail changes may be made without departing from the scope thereof.

In the drawings,

Figure 1 represents, a vside elevation in section, illustrating the manner in which the device is to be used for stropping the blade, and illustrating the cutting edge of the blade, both in full and in dotted lines in stropping relation to the strop.

Figure 2 represents, a. rear elevation of my improved device.

Figure 3 represents, on an enlarged scale a fragmentary sectional elevation illustrating the manner in which the pivotally-supported blade holder support is pivotally secured to the body or frame of my device.

Figure 4 represents, a side elevation of my improved device, illustrating the pivotallysupported bladeholdersupport which carries the'blade holder in shaving relation to the frame.

Figure 5 represents, on an enlarged scale a plan view of the blade holder and blade; and Y Figure 6 represents, Va sectional view of the same'taken on line a-a looking in the dii rection indicated by the arrow.

Similar numerals of reference refer to like parts throughout the specification and drawings. y

AIn the drawings, 1. represents the body or frame of my improved device, which body or frame may be stamped from sheet metal or the like, and afterwards bent into the desired shape as shown.

Said body or frame comprises preferably a curved body portion extending cent-rally and lengthwise of the frame, the two opposite ends of the frame being provided with two downwardly extending lugsf or ears 2 andy parallel each to each. Y v

.The frame 1 is constructed toy grip the blade at the vfront corners, the sharpened edge of the blade resting upon the bentover end of the guard 4, which isprovided with the usual perforations 5, the free end of which is bent downwardly, and which is sufficiently inl advance of the vedge ofthe blade to afford the necessary protection n against accidentalcutting.

The forward and outer end of the guard i 4 -has upwardly extending stops 6 for engagement with the corners of the ycutting' edge of the blade, to preventsaidv cutting edge from projecting too far beyond the guard 4, to at all -times maintain the cutting' edge ofthe razor in the proper and adjusted position relative to the guard teeth.

These stops 6 may, for convenient sake, be formed integral with the frame l, or secured thereto in any convenient or desired manner. n

The rear edge of the body or frame-1 is preferably bent downwardly, and to the end of which` is secured a removable handle 7 which, if vdesired for convenience in packingzcmay be detached from the frame.

The pivotally-Supported blade holder support comprises two opposite side-portions 8 and 9, parallel each to each, and connected at its lower end by means of a cylindrical rod 10, preferably located on the underside of the body or framel, the ends o-f which pass through the apertured ears or lugs 2 and 3 and riveted to the side portions 8 and 9 as clearly indicated in the drawings, see Figure 3 of the drawings.

Journalled in the side portions 8 and 9J of the blade holder support intermediate of its end is a roller 11 to be engaged by the strop when the device is used for stropping the blade as illustrated in Figure 1 of the drawings.

Also j ournalled in the side portions 8 and 9 of the blade holder support is a cylindrical rod or shaft 12 which carries the blade holder 13, which holder may consist of a piece of sheet metal wrapped around. said rod or shaft 12, and secured thereto in any convenient or desired manner, so as to provide resilient clamping jaws 14rand 14 to receive the razor blade 15 between themselves, as has been common in general heretofore.

The side portions S and 9 have upper and lower holes forming bea-rings for the ends of the cylindrical rod or shaft 12 and the roller 11, bothextending transversely of the blade holder.

rlhe rod or shaft 12 and the roller 11 are connected by means of pinions or gears 16 and 16, so that by drawing the device along the strop will tend to turn the upper rod or shaft 12 carrying the blade holder 13, and when the direction of sliding the device is reversed the said upper rod or shaft 12 will be turned according to the principles alreadywell understood inthe art.

The plane portion of theblade is provided with a central aperture 17 conveniently located therein, adapted to engage with a roller 18 conveniently carried on one of the clamping jaws 14 of the blade holder 13, to firmly secure and prevent the accidental displacement of 'the blade from said holder.

The razor blade, as shown, is preferably made from sheet metal provided with a longitudinal cutting edge, but l wish it to be understood that razor blades of peculiar construction may be employed.

Pivotally secured in the aligned bearings 19 formed integral with the body or frame 1 is the latch plate 2O preferably made from a single piece of suitable material, `the ends y of which are bent around to engage with said bearings.

The central portion of said latch plate is provided on its inner side with an engaging element 21 designed to bear upon the rear face of the roller 11, in order that when said latch plate is manipulated by means of the finger piece 22 formed on the latch plate, the cutting edge of the blade 15 is brought into an adjusted operative position relative to the guard.

The two opposite ends of the frame 1 are recessed so as to provide stops 24 formed on the ends of said frame so that the movement of the two opposite side portions 8 and 9 of the pivotally-supported blade holder support is limited in its forward movement.

rlhe rearward movement of said pivotally-supported blade holder support is limited by' the roller 11 engaging with the rear end of the frame 1 in which the aligned bearings for the pivoted latch plate is secured. y

The movement of the pivotally supported blade holder support is only limited in its forward and rearward direction as just described when the razor blade is released from the guard of the frame for cleaning the same.

During the stropping operation the forward and rearward movement of the pivotally-supported blade holder support is limited by the strop.

T he operation of the device is as follows: a safety razor blade is inserted between the resilient clamping jaws 14T-14 of the blade holder 13; the strop 23 is then passed over the body or frame 1, through the pivotallysupported blade holder support and under the roller 11 on said blade holder support, and then out through the other end of the frame l of the device as clearly indicated in Figure 1 of the drawings.

The attaching end of the strop (not shown) is hooked over any suitable support while its opposite end (likewise not shown) is held in one hand. The other hand grips the handle T of the device, and reciprocates 100 said device back and forth along the strop, thereby permitting the edge of the, blade to be engaged with the strop.

The present invention provides a very efficient and exceedingly simple and inex- 105 pensive device, the same being constructed of a minimum number of parts, which are of such a shape as to lend themselves ready to manufacture by the use of suitable punches and dies from ordinary sheet metal, and 110 lwhich parts are reduced to the simplest op erative efficiency; and further, the invention provides a safety razor in which the accidental cutting or injuring of the strop by the blade is prevented.

Experience has demonstrated that the organizationabove described is a highly efficient one, andl while I have shownk the preferred embodiment of my present invention, l do not wish to be limited to the eX- act details of construction shown and described, as obvious modifications thereof. not involving the exercise of invention, may be made by any skilled mechanic. and such departures from what is herein set forth, 1 consider within the scope and terms of my claims.
